The time it takes for a phone to charge is largely unaffected by whether the phone is on or not. It might be possible to argue that a phone that is on is using power from the charger to run the phone and to charge the battery, and therefore won't charge as quickly. But the contemporary chargers will generally supply enough power to charge the battery at the "prescribed" rate regardless of whether or not the phone is on. And they'll also supply the power to operate the phone while simultaneously charging the battery at the maximum (optimal) rate.
